Good Day,
Hopefully some of our Stainless experts will chime in soon.
Meantime, this will depend upon many factors. Not the least of which is the exact grade of SS, the thickness, the heat from which air forced cooling was commenced, how fast the temp was pushed from point A to point B, and others I probably have not mentioned.
The experts will be able to give you better information with some additional facts presented by yourself.
Have a Great Day, Brent
